New precast constructions for integrated complex urban interventions / Neue fertigteilkonstruktionen für integrierte komplexe städtische interventionen

The world of construction today requires a series of sophisticated technological solutions needed to fulfil technical specifications that are becoming more and more stricter and wider. The traditional cast-in-situ concrete constructions, relying on a semi-artisanal work, struggle to reach these objectives. A partial prefabrication in concrete made with precast systems with wet joints only partially addresses this issue. It is our opinion that the near future of concrete technology is going to be based on a process that avoids as much as possible the uncertainty coming from handicraft, granting the needed quality of construction and providing it in short times. The natural way to commit to this view is to improve the industrialisation of the construction process, taking advantage of the multiple innovations allowed by dry assemblage procedures. The paper describes a complete solution for rapid complex urban interventions characterised by a high level of industrialisation. This solution includes precast systems for residential, commercial and industrial buildings, produced in a unique plant. The structural optimisation of components, automatisation of design process, and innovative production techniques imprint robustness, speed of construction and high competitiveness to the precast products.
